Biography of Roger L. Kaesler

Born June 22, 1937 in Oklahoma, Roger LeRoy Kaesler earned his bachelor's degree in geological engineering from the Colorado School of Mines in 1959. He completed his master's and PhD degrees in Paleontology from the University of Kansas in 1965 and immediately joined the Department of Geology faculty. Kaesler's more than 40 years of service at KU included stints as Director of the KU Geology Field Camp in Canon City, Colorado; Director of the Paleontological Institute; and Senior Curator at the Natural History Museum and Biodiversity Research Center.

An expert on Ostracoda (small crustaceans with a nearly complete fossil record and 8000 living species), Kaesler published prolifically and served as editor for 13 issues of the Treatise on Invertebrate Paleontology. He was the curator for Lindley Hall's weekly display, Rock of the Week.

Kaesler was appointed Fellow of the American Association for the Advancement of Science, the Paleontological Society (USA), and the Geological Society of America. He received the Geological Society of America's Distinguished Service Award and awards from his two alma maters, the Colorado School of Mines and KU.

Kaesler married Jerelyn Boudreaux, and they had three children: Jane Stotts-McCall, Andrea, and Stephen. Roger L. Kaesler died August 11, 2007, after retiring the previous year.

Scope and Contents

The bulk of this collection consists of professional correspondence, roughly arranged in chronological order by year. Early years often only occupy a single folder, and because Kaesler organized his papers chronologically, there has been no effort to separate them by subject matter. The rest of the collection contains materials related to special projects Kaesler worked on, notably scholarly publication efforts.
